Constraints on Dark Matter Self-interactions from Weak Lensing of Galaxies from the Dark Energy Survey around Clusters from the Atacama Cosmology Telescope Survey
Self-interactions of dark matter particles impact the distribution of dark matter in halos. The exact nature of the self-interactions can lead to either expansion or collapse of the core within the halo lifetime, leaving distinctive signatures in the dark matter distributions not only at the halo ce...
